if you don't have a passenger-side airbag, it's easy... if you do, it's a pain in the bum.
If no airbag, there's a side screw accessed through the glovebox and then an allen screw accesed through the vent. Then I think there's 2 clips that need to be released just inside the vents and it then the assembly slides out. Bulb is behind plastic flap.

Same for airbag models, except the airbag has to come out to get to the screw!
